This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

4 findings rated critical or high. Fix these first.

  1. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

The website holds a strong market position in the Czech online media space for culinary content, leveraging a broad network of partner media sites. Its business model is advertising-driven with additional user-generated content features and newsletter subscriptions. The target audience is broad, encompassing general consumers interested in cooking and food. The site demonstrates consistent branding and professional content quality, supporting its credibility and user trust.

Security posture

The site enforces HTTPS and employs modern security practices including Google reCAPTCHA v3 and a consent management platform (Didomi) for GDPR compliance. While explicit security headers like X-Frame-Options and X-Content-Type-Options are not visibly set, the overall security posture is good with no evident vulnerabilities or exposed sensitive data. The use of multiple third-party scripts and ad networks is managed with consent mechanisms, reducing privacy risks.

Recommendations

  1. Implement explicit security headers such as X-Frame-Options and X-Content-Type-Options to enhance protection against clickjacking and MIME sniffing.
  2. Regularly audit and update third-party scripts to mitigate risks from vulnerable libraries.
  3. Enhance accessibility features to meet higher compliance standards and improve user experience for all users.
  4. Consider publishing a security.txt file and a dedicated incident response page to improve transparency and readiness.
  5. Maintain and update privacy and cookie policies to reflect evolving regulations and user expectations.

Technical notes

Notes

The website uses a modern technology stack including jQuery, Google Tag Manager, Google reCAPTCHA, and advanced ad serving technologies such as Prebid.js and Rubicon Project. It is built with responsive design principles ensuring good mobile optimization. Performance is moderate with asynchronous loading of scripts to improve page load times. SEO is well addressed with proper meta tags, Open Graph data, and structured JSON-LD for video content. The site lacks explicit CMS identification but appears professionally maintained with a robust infrastructure.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
